So far ir seems most of the bugs that are being seen are fairly minor, but I will say, not knowing if everyone wiped or not, this is exactly why I wipe everything with multiple passes when flashing a new rom, or for that matter when restoring a nandroid as well, even if Im flashing the same build 2.3.4 or even by the same dev, the way I see it, if there is even the slightest chance it might save me from problems later, why not take the time & do, versus having to make time to do it again later, when u start with whats right, a clean slate, yor better off imo.
